Q. A cube is shifted to a depth of 100 m in a lake. The change in volume is 0.1%. The bulk modulus of the material is nearly
A) 10 Pa
B) $10^{4}\ Pa$
C) $10^{7}\ Pa$
D) $10^{6}\ Pa\ $
Explanation
(d) 10 m column of water exerts nearly 1 atmosphere pressure. So, 100 m column of water exerts nearly 10 atmospheric pressure, $ie,\ 10\ \times 10^{5}\ Pa\ or\ 10^{6}\ Pa.$
